ADDITIONS TO THE WYCOMBE FLORA. 61 
The Marsh Cinquefoil (Comarum palustre), like the three 
preceding species, is new, not only to our district but to the 
county. Mr. Latimer Clark included it in a list of plants which 
he had observed growing near Marlow; but I have been unable 
to ascertain further particulars respecting it. While in Cheshire 
I was much struck with the abundance of this plant as affording 
an illustration of a species rare in our county, but there one of 
the commonest; it grows by, and in, every pond or pit in the 
neighbourhood of Mobberley. 
The Butcher's Broom (useus aculeatus) was discovered by Mr. 
Marshall, near Cores End, and by him recorded in vol. i, p. 190. 
It is new to the district, but not to the county. 
We may now turn our attention to a few of the rarer plants 
which have been observed in fresh localities during the past year. 
First in importance comes the Mezereon (Daphne Mezereum), which 
has this year been observed in two new places—in the Braden- 
ham Woods, by Dr. Bowstead, who recorded the discovery in 
vol. i, p. 194, and at Hazelmoor, by Mr. Marshall. Mr. Latimer 
Clark has furnished me with the following note relative to its 
former occurrence in our district:—‘‘ Daphne Mezereum grew 
thirty years since sparingly in the woods about a mile and a half 
from Penn. At that time we could find only four or five plants, 
and those large and old ones, as the cottagers removed the small 
ones for the purpose of pianting them in their gardens, It also 
grew at the same period, very sparingly in the woods between 
Marlow and Loudwater. Ihave also once seen it on the Berk- 
shire side of the river. From its attractive appearance, and the 
love of gardening which has now become so general, I have no 
doubt it has been eradicated by the cottagers.” I have else- 
where* entered more fully into the question of the nativity of 
this rare plant, and therefore need only remark that the more I 
investigate the subject, the more convinced I am that in Buck- 
inghamshire at least, it has every claim to be ranked as a genuine 
British species. Next in importance we may rank the Deptford 
Pink (Dianthus Armeria), found by Mr, Marshall in a small wood
